Differences on post-fire regeneration of the pioneer trees Cecropia glazioui and Trema micrantha in a lowland Brazilian Atlantic Forest

A study of natural post-fire succession was carried out in a disturbed vegetation around fragments of the Atlantic Rain Forest (National Biological Reserve of Poço das Antas (22°30’-22°33’S, 42°15’-42°19’W), Rio de Janeiro State). All the pre-fire individuals of Cecropia and Trema in the area were n...

Todos los individuos de Cecropia y Trema previos del fuego en el área fueron numerados con marcas plásticas. Se realizaron otros dos censos, 3 y 12 meses después del fuego con el objetivo de detectar mortalidad y buscar la presencia de nuevos brotes. Las especies dominantes fueron: Pteridium aquilinum, Panicum maximum, Trema micrantha y Cecropia glazioui. Pocos días después del paso del fuego, los pastos y helechos se dispersaron por el área, mientras que los troncos de Trema y Cecropia estaban completamente quemados. La mayoría de los individuos de Cecropia produjeron algunos rebrotes mientras que la mayoría de los individuos de Trema murieron. Sin embargo, un gran número de plántulas de Traem fueron reclutadas mientras que únicamente una plántula de Cecropia fue observada durante el período de un año. La mayoría de estos plántulas murieron a lo largo del año, mientras que los brotes se estan ya reproduciendo. Los usos de Cecropia en lugares donde el fuego es recurrente puede ser más apropiado debido a su mayor chance de sobrevivir y a su habilidad de recuperarse más rápido después del fuego A study of natural post-fire succession was carried out in a disturbed vegetation around fragments of the Atlantic Rain Forest (National Biological Reserve of Poço das Antas (22°30’-22°33’S, 42°15’-42°19’W), Rio de Janeiro State). All the pre-fire individuals of Cecropia and Trema in the area were numbered with plastic labels. In order to check for the presence of new sprouts and mortality, two other censuses were carried out, at 3 and 12 months after the fire. The dominant species were: Pteridium aquilinum, Panicum maximum, Trema micrantha and Cecropia glazioui. Few days after the passage of fire, grasses and ferns spread their area, while the stands of Trema and Cecropia were completely burned. Most of individuals of Cecropia produced some sprouts while most of individuals of Trema died. However, a great number of seedlings of Trema were recruited while only one single seedling of Cecropia were observed during a period of one year. Most of these seedlings died through the year while the sprouts were already reproducing. The uses of Cecropia in places where fire is recurrent could be more appropriate because of its higher chance of survival and faster recovering ability after fire Universidad de Costa Rica 2005-06-01 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Article application/pdf https://revistas.ucr.ac.cr/index.php/rbt/article/view/14291 10.15517/rbt.v53i1-2.14291 Revista de Biología Tropical; Vol. 53 No. 1-2 (2005): Volume 53 - Regular number 1-2 – March-June 2005; 1–4 Revista de Biología Tropical; Vol. 53 Núm. 1-2 (2005): Volumen 53 - Número regular 1-2 – Marzo-Junio 2005; 1–4 Revista Biología Tropical; Vol. 53 N.º 1-2 (2005): Volume 53 - Regular number 1-2 – March-June 2005; 1–4 2215-2075 0034-7744 10.15517/rbt.v53i1-2 spa https://revistas.ucr.ac.cr/index.php/rbt/article/view/14291/13566 Copyright (c) 2005 Revista de Biología Tropical http://creativecommons.org/licenses/by/4.0
